Web Forms :: Scaffolding With Exist Application
Apr 4, 2010
I need your advises regarding the scaffolding with my current application, I use ASP.NET Web Application from the menu but later on I would like use scaffolding top-up the exist application. I am NOT sure, Can I use scaffolding with my exist application without need going to Dynamic Data Web Application? BTW: my application needs users registration and authentication based on ASP.NET solution, and this will NOT work with Dynamic Data Web Application.

I finished my asp web application with SQL Server DB, and now it is the time for template "design". I read about mater pages, but it seems not for exist web application, it seems use it before start coding which is the first step in the project. I did mistake which I missed this step because I am new in ASP.NET world. Which solution useful as template for my current web application? my application contain around 11 ASP pages and might be increase. I am thinking to do it page by page, but still I try find-out good solution. Is their any way to use sample template with my exist web application?

I am using Asp.net 3.5. In my application I am handling errors at application level in Global.asax. I am using 3rd party control FpSpread in my application. In all the pages where I've that control, it's throwing "File does not exist" error when first time postback occurs in IE (on every postback in FF). From the log I got following Details:
04/01/2010 11:32:18 : The error description is as follows : [URL]
Type- System.Web.HttpException
Message- File does not exist.
Stack Trace- at System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response)
at System.Web.StaticFileHandler.ProcessRequestInternal(HttpContext context)

It is trying to refer wrong URL because my css is in App_Themes/Blue directory and my page is in /Forms/Company directory. Has anyone encountered similar issue before?? Is this the issue related to theme?? I am not trying to load any images programmatically.

I've written a singleton class that exposes the web.config properties in a nice get property kind of way.
I want a Load method to parse the data in the config and set the public properties, and I want to throw exceptions (so they are logged in the EventLog) when a configuration key is missing or can't be parsed.
I tried placing the Load() code in Application_Start of the global.asax but then remembered this will only be run once, or until the application restarts.
Where is the best place to put code that you need to run 'everytime' your site is started/run by the user? I basically want the website to stop functioning if certain config properties cannot be loaded.

I'm using VS 2008 Pro SP1 with ASP.NET MVC 1.0. When I try to create a strongly typed view, I cannot choose a model class. If I type the class name manually, the view type listbox is disabled, any previously chosen value is reverted to Empty.

With the help of this excellent step-by-step guide (http://jon-ilgrim.blogspot.com/2008/10/aspnet-mvc-web-site-template.html), I was able to convert an ASP.NET Web Site to be MVC enabled. However, I do not get all those nice wizards - for example, right-clicking in the project area and selecting Add -> Controller or -> add View.There are several sites that describe enabling this by adding a ProjectTypeGuid in the project file, but web sites do not have a project file.Is there anyone out there who has gotten this working in a Web Site?

I was reading this article, http://weblogs.asp.net/scottgu/archive/2010/01/10/asp-net-mvc-2-strongly-typed-html-helpers.aspx, and that looks very interesting. However I wonder if there is a way, or probably attribute, available with which I can prevent auto scaffolding of certain properties of my model?

Is there any existing software for generating a UserControl from a table of a database?
For example, my table contain 3 fields : name , last name , age.
The software generates a user control that has 3 labels and textboxes with validation and submit button and a gridview for displaying information , etc..

Can I seek some advice here if I want to incorporate some automated scaffolding in my MVC 2 web application what is the best way to go? Should I be considering: MVC 2 Templated Helpers, or Dynamic Data (with support for Entity Framework) Roughly speaking I want to layout my own website layout in MVC 2 but then:
for high usage use cases custom define the page, for CRUD maintenance pages hook the website menu to point to some scaffolded auto-generated pages (i.e. it is for this item that I ask the above question). I've had a look at the Dynamic Data pages where you can add/edit/delete all aspects of an EF entity, so it's this type of thing I'm after (e.g. have an Edit Person menu link that when click launches an auto maintenance page for Person)

The partial class:
[Code]....
In the controller:
[Code]....
Shouldn't ScaffoldColumn(false) hide the field in the view? I create a strongly typed CREATE view (AddSO), expecting that the soID column won't be rendered and that the Label name of the field 'name' will be 'Full Name'. But the AddSO view renders the soID column and still labels the 'Name' field as 'Name. What am I doing wrong?

I am using the Html.DisplayFor() and Html.EditorFor() helper methods to auto-scaffold a Display view and Edit view for a Municipality entity.
My Application layer is used to retrieve a Municipality class:
[Code]....
For the Display view this entity is mapped to a DisplayMunicipality class containing Display meta data:
[Code]....
For the Edit view this entity is mapped to an EditMunicipality class containing Edit meta data:
[Code]....
This works fine but it requires a lot of extra code, not only the code mentioned above but also all kinds of conversions inside my controller.
Is it possible to put the meta data in the Municipality class that is returned from the Application layer? In that case I need some mechanism to specify that a property should be shown in the Display view or Edit view.

I don't know if this is possible but I would like to customize some of the HTML helpers autogenerated in the template. For example, I would like to replace the LabelFor with something that will allow me to specify an image with the label and also a ToolTip property so when you hover over the label you get the tool tip.

When debugging my application, I m getting an application level error in global.asax file. The Server.GetLastError() reads "File does not exist." but thats it. No more details on the filename or the location where the code is trying to find a file. I commented out the application_error method, with a hope that the exception would be thrown when the debug the application, but no errors were thrown. How do i find the source of the error, cos I want to resolve this issue by either putting the file that the application is looking for or by completely removing the code that is referencing the file.

I just got a new desktop computer with Windows 7 Pro as the operating system. I installed Visual Studio 2008 on to this new computer and tried to open a previously existing ASP.NET 3.5 solution that displayed perfectly fine on my previous computer (this previous computer used the Windows XP operating system, IIS6, and IE7 browser). However, in Windows7/IE8, I'm receiving the following error:
Server Error in '/' Application.
Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: The file '/MasterPages/MainMaster.master' does not exist.
Source Error: Line 1: <%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="default.aspx.cs"[code]....
when I tell you that the file '/MasterPages/MainMaster.master' file does, in fact, exist. In addition, this file's location is properly referenced in the code (as indicated in Line 1 above), and as I said, was displayed properly by the browser in my previous computer. It might also be helpful to note that I've tried to navigate to other pages in this site, and this browser displays the same message for any and all master pages located in my MasterPages folder. In summary, for some reason the browser cannot see any pages in the MasterPages folder. Can anybody tell me why I'm getting this error message when the folder and file is exactly where default.aspx says it is?

I have found the error below in my web log and I wonder what the cause may be.
The page indeed does not exist at the requested location.
Perhaps a request is incoming and ASP.NET is trying to compile that page?
But, I did not know a request to a non existing page would cause a compilation error.
Error: The file '/<X>/<Y>/<Z>.aspx' does not exist.

System.ArgumentOutOfRangeException: 'DropDownList' has a SelectedValue which is invalid because it does not exist in the list of items.this question has been for a long time ago but seem no actual answer for it except for catching the exception.I don't want just catch error instead of check first whether the value exist in drop down list. My scenario was different from the other. my data source is bind to a datatable, all is in hard code.

I get the message "The name DropDownList1 does not exist in the current context". Without using a master page, I can get it to work. It's when I bring this code over to a master page is when I get this error. I'm trying to auto populated a drop down list. Here is my code...

This isnt a project, I made a New Website. I can't figure out why this will work outside of my master page and not in .
Oh and im not putting this code inside the SMC.master.cs file, It goes inside my Tool.aspx.cs file
